Meu drive USB não é reconhecido automaticamente depois que o Linux (CentOS 7) é inicializado, mas depois de remover e inserir o pen drive USB, ele é reconhecido.
Como posso configurar uma detecção USB apropriada no boot do Linux?
$ ls /dev/sd*
/dev/sda /dev/sda1 /dev/sda2
Aqui, o USB foi removido e inserido manualmente.
$ sudo tail -f /var/log/messages
